We combine our circuit board repair expertise with state of the art tools for a complete and robust repair of the problems that plague the CPC modules. Unfortunately DIY solutions and repair shops with inferior tools and techniques often cause more damage to these controllers. If a repair has already been attempted by a non-qualified facility, we will evaluate the damage to determine if additional costs are necessary. In such cases, we will contact you before performing the repair to discuss your options. If there are additional costs due to a prior repair attempt and you choose not to proceed with the repair, a full refund will be issued.
Sometimes when the circuitry on your CPC4 fails it also corrupts the programming on the circuit board. Despite that failure, we are able to fully repair this module by reprogramming it to the latest OEM configuration for your vehicle based on your particular VIN. Your CPC4 will be ready to install and use immediately without additional programming. If you have any questions, feel free to call us at 800-547-2049.
